Applicationv led November 13, 1,914. Serial No. 871,990.

= a specification, like reference characters on tion constitutes a continuation` in part oifinyf the drawings indicating like parts in the several figures. v f H rIhis invention relates tomachines for set-- ting eyelets.` The invention is herein set` forth in its application to the clenching of eyelets between two layersof an article oif work, which operation in the manufacture of boots and shoes is known blind eyeleting or invisible eyeleting. This applicacopending application ySerialy No. SAABS, led August l, 1914. v

An object of the invention is to provide improved mechanism by which the insertion of-blind or Iinvisibleeyelets may be facilitated. e A p,

In accordance with a feature of the invention, the illustrated eyeletsetting tool has a clenching shoulder formed and arranged to pass through a lacingv hole Ain one or more layers of an article of work so as to clench an eyelet between two layers of the article. Said tool is provided with an `abutmentbehind the eyelet-clenching or4 :upsetting shoulder. In the illustrated embodiment ofthe invention, the abutment behindcthe upsetting shoulder of the eyelet-clenching tool and the said upsetting'shoulder are relatively adjustable lengthwise of the clench-i ing tool. In the illustrated construction the said abutment is also slidabl'y moi'iute'l and spring-pressed toward the work to give it a considerable capacity tork seli-accoinmodation to different work thicknesses.

Also in the illust-rated embodiment ofthe invention there is a contracted or reduced portion immediately behind the upsetting shoulder of the eyeletfclenchingtocl. This construction renders the end ofathe eyelet barrel less likely to catch inthe under surface of the upper layer during the setting operation. v

- The present invention is herein illustratedl as embodied in a machine of the typeshown,

ttor example, in United States Letters Patent No. 603,023, granted April 26, 1898 on application of Seymour Field, which machine is organizedy to provide for punching the eyelet-receiving holes by a tool separate tromthe .eyelet-settino' tool. It is to be understood, however, that theinvention in various of its aspects is not limited to embodiment in a machine 'of this type.'

For a full understanding oi the present invention reference is to be had to the fol` lowing' description and thel accompanying drawings, in which- Figure l is a view in perspective showing a setting device embodying the invention and a punch as they are arranged in an eye `leting machine, to 'ether with a piece of work being operate upon;

Figs. 2, ,3 and A are enlarged views illustrating the operation oi inserting and clenching an invisible eyelet; and k Fig. 5 is a vertical sectional view through the setting device.

When the setting device is used in a ma chine of the type shown in said Field Patent 603,023, the lacing holes are punched by a separate ypunch provided for that purpose, the setting device being utilized to 'feed the work from the punching locality to the eyelet-receivinglocality,as a step in each cycle of operations. It isV unnecessary to illustrate the construction of the machine itself, and for the sake of clearness it is omitted lfrom'the drawings, The machine is pro, vided with a support for the work and with a punch which is operated preliminarily` to theinsertion of the eyelet to form the eyelet hole. As shown inFig. l the punch K is located atthe right hand side of, the setting device A. When the punch has performed its function it is retracted so that the setting diemay be moved to the right, inserted in the hole and thenzmoved to the left to 'feed work and register the hole with the lower die E.

The upsetting die consists in a curved up` setting shoulder 1 of such shape as to cause the end ,of the eyelet barrel forced against it to be spread or flared outwardly, and is of such diameter that it may be passed through one or `more layers so as to ciencb the eyelet between two of the layers. The clenching position of the upsettingshoulder 1 is cleanly shown in Fig. 2. F upsetting ehbulder L the settingA vi' is provided with a recess H or contracted portion of, substantially less Idimm-,ter than the diameter off the upsetting shoulda, .Corisequntly, when the setting device is insert'- ed in the work, the upper layer will be momentarily stretched by the upset droid* der 1 and will then loosely surroun the recess il. Above the recess Hure Seam :device is provided with an elon ated stem aving' an enlarged threaded rtio'n 2 at its upper end to receive" adiive'r. The portion 2 of the setting device isscrwed into a sleeve B which is'inadeirisnchsliape and size as zo at readily -irwsfth'e lever diother carrier of an eyeletiiig max: inein place of the' upsetting toer oralnarily used;

Surrounding the` lower end of the si'eeve B and disposedwith its ldwef end 'sdihev'ehat above thelipsetting shoulder 1l of thefsettiiig device'A is an adjustable sleeve or abutment C.' Thislmember is shaped-atits lowrf'e'd' to bear lupon the surface'dftlie upper ltyer ofI the'vvorkl and' to flatten' th riiatelland also the clenched endo tlle'e'yelt barrel; so that a very smooth ap carence is' imparted to the finished Work. emeinbr Ci provided With a longitudinali Slot 4 in one side,y through whit: psed a'Srw 5 threaded* into the sleeveB'; A` stiif-i cornlower end' of1 the sleeve 6' and an interior shoulder formed near the-fbott'oigi of the member C. The springd; tliereibre,` normally holds the member@ inf its lowerniost position, this position' being determined by the engagemlntof thescrvv 5 with the up-` only so arias is necessary tti-:insure the end' of the eyelt" barrel being clehichedbeltiiltT beneath it. l As stated in myfprevious, a plication, the miberC maybe clipedli any' desired position, andthe operation of tli spring 6 eliminated if thel requirements ofI the work'arebetter sei'ved'y Bysiich ari'an'gement of the parts. In4 any. case, sincftlxe member C is used to determine' thevvorking relation ofthe shoulder land thefeyeltf-receiving layers its pcsiuchrellrtivly tothe shoulder will be adjusted according'to the thickness of the material throughl which the shoulder must pa'ss to reach the desired Working position. n

Adjustment of the position of the setting shoulder l and recess H with Iespect to the acting face of the member C may be eiiected by screwingpthe setting device A into or out of the sleeve B, the' slot 3' being readily accessible for this purpose.` Astle work varies in the thickness of its layers, and also va the in their number; ibis i the setting device, and on account of the adjustments h .disclosed .ith A been found prenait. dirigir ruzies or invisible eyeltwoi: such varieties' as are passed through a', large factory in the regulng'ponmc-of manufacture.
